This is what happens when you put Alkali metals in water







And now in poem form:
To prove Pythagoras was right
With new-found ease and much delight, --
Let's say hypotenuse is c,
With one leg a and 'tother b.

On c we draw a square with pride,
Then triangles on every side.
The square of (a + b), you see,
Is c squared plus two times ab.

Equate and cancel 2ab
--- And we have reached the Q.E.D.

Bach is not amused!


Mozart: Rebelled against authority, became an alchoholic, died at 35...like a rockstar!


Beethoven is working. Do not disturb!


Haydn. A museum had his mummified head for a while. That's creepy.


Wagner: He wrote a bloody long opera

Paul Erdos: The man who was high on math. And stimulant drugs, such as amphetamine.


Proof of the infinitude of prime numbers by Reductio ad absurdum

Assume P1 = 2, P2 = 3, P3 = 5 and so on
Assume Pn to be the largest prime.
Let Q = (P1xP2...xPn)+1
By construction, Q is not evenly divisable by any element of (P1xP2...xPn) So Q must either be a prime larger than Pn or be divisible by a prime larger than Pn. (By the fundamental theorem of arithmetic, every number is either a prime number or is expressible as a product of prime numbers) Thus, Pn is not the largest prime, contradiction.

extra points if you know who this is
